And you wonder why you gernaded your trans....
Lanny my black magic grenaded my trans. Just as it will yours when it comes time installing one in your car

My first gear sheared to nothing, bent ALL my syncros and broke teeth off my pinion.
That boat anchor disc is a formula of bending syncros even when you dont powershift. Others have also mentioned this.
Black magic with a stage 1 are for cars with over 350+ and a pro-ring trans IMO.
A wheelie pic is extremely expensive

If your gonna use a black M you must shimm the hell out of it so it will slip. If you dont you'll regret it. Shimming will make that pedal feel stiffer though.
